Abstract

A rubber sheet includes: a main body fitted to a mounting portion formed so as to be depressed at the spring guide, the main body supporting a coil spring; and lips formed to project from respective side surfaces of an inner periphery and an outer periphery of the main body in a radial direction, the lips being configured to abut on the spring guide to prevent a foreign matter from invading between the main body and the mounting portion.

First claim

The invention claimed is:

1. A suspension device, comprising:
a shock absorber configured to be disposed between a vehicle body and a wheel;
an upper mount mounted on a distal end of a rod of the shock absorber;
a spring guide mounted on an outer peripheral surface of the shock absorber;
a coil spring disposed between the spring guide and the upper mount for elastically supporting the vehicle body; and
a rubber sheet disposed between the coil spring and the spring guide, the rubber sheet has an arc shape or an annular shape, wherein
the rubber sheet includes:
a main body fitted to a mounting portion of the spring guide to support the coil spring, the mounting portion having an annular shape; and
lips projecting from respective side surfaces of an inner periphery and an outer periphery of the main body in a radial direction, wherein the lips abut on the spring guide to prevent foreign matter from invading between the main body and the mounting portion,

the spring guide includes:
a protrusion projecting toward the upper mount; and
an outer circumference having an annular-shape and arranged at an outside of the mounting portion in the radial direction,

the lips include:
an inner-peripheral-side lip projecting inwardly in the radial direction from a side surface at an inner peripheral side of the main body; and
an outer-peripheral-side lip projecting outwardly in the radial direction from a side surface at an outer peripheral side of the main body, and

during extension and contraction of the coil spring, the inner-peripheral-side lip and the outer-peripheral-side lip are kept abutted on the protrusion and the outer circumference of the spring guide, respectively, from above.

2. The suspension device according to claim 1 , wherein
the lips are disposed throughout a whole circumference of at least one of the inner periphery and the outer periphery of the main body.

3. The suspension device according to claim 1 , wherein the rubber sheet further comprises
a rising portion disposed on the inner peripheral side of the main body and projecting toward the upper mount to support an inner periphery of the coil spring.

4. The suspension device according to claim 1 , wherein
a bottom surface of the main body of the rubber sheet abuts on the mounting portion of the spring guide over an entire surface of the bottom surface of the main body of the rubber sheet.

5. The suspension device according to claim 1 , wherein
the inner-peripheral-side lip and the outer-peripheral-side lip are formed so as to be inclined to the protrusion and the outer circumference sides, respectively.
